2. OPERATIONAL EQUIPMENT
a. CENTRAL CONTROL PANEL AND PEDESTAL.
(1) WING FLAP AND LANDING GEAR CON-
TROLS. - The wing flap motor is controlled by a
toggle switch. The time required to lower the flaps
at 147 mph is between 15 and 30 seconds.
WARNING
In returning the flap control switches from
“DOWN” to “OFF,” be sure the toggle switch
is not allowed to snap to “UP,” resulting in
immediate retraction of the flaps.
(2) The main landing wheels and tail wheel are
operated simultaneously by a toggle switch. A hinged
guard prevents accidental moving of the switch to the
“UP” position. Warning that the landing gear is not
fully extended is given by a green indicator lamp fail-
ing to light, and by a horn which sounds if any throttle
is closed.
(3) COWL FLAP VALVES. - Cowl flaps are op-
erated by four valves, each valve controlling the flaps
on one nacelle. The valve must be turned to ‘ ‘LOCKED’
when the desired position of the flaps is reached.
Slight “cracking” of the control valve will result in
relatively slow travel of the flaps when close adjust-
ment is desired.
(4) FUEL BOOST CONTROLS. - The fuel boost
pumps, operated by four toggle switches, provide fuel

and also prevent vaporization in the lines to engine-
driven pumps due to hot fuel or high altitudes. Booster
pressure at the No. 3 nacelle fuel strainer also supplies
fuel to the priming system.
